Rapid scan ultraviolet spectroscopy of the formation of 1,1- and 1,3-complexes. Reaction of 1-methoxy-2,6-dinitro-4-trifluoromethylbenzene with piperidine, pyrrolidine, and n-butylamine in dimethyl sulphoxide

Abstract

Rapid scan u.v. spectra for the reactions of 1-methoxy-2,6-dinitro-4-trifluoromethylbenzene with piperidine, pyrrolidine, and n-butylamine in dimethyl sulphoxide have been observed. The formation not only of 1,1-complexes but also of 1,3-complexes has been confirmed. Equilibrium constants for the formation of the 1,1- and 1,3-complexes have been determined and compared with data for the related systems.
